VSDIF is rated the best duplicate image finder on major photography and software magazines and technology web sites.

What is so special about Visual Similarity Duplicate Image Finder?
As the name already suggests this tool can find duplicate and similar images based on content analysis regardless of the image format, size, dimensions, colors and other image attributes. What this means is that even if you have copies of the same image with modifications applied like color correction, crop, retouching, change of file format or watermarks it will still be identified as a duplicate of its original image. This is a task that a standard duplicate file finders cano not handle. The tool supports more than 100 common image formats including Photoshop PSD, plus over 300 RAW camera formats.

Processing large image collections is extremely fast using the new cache system. The tool will analyze the image data and collect it in a cache that will be reused in consequential scans. The cache system checks the images for modifications. This means that if a photo is edited it will be re-processed automatically and the updated version will be used for the comparison. The “Image Search” functionality can find images similar to a sample photo. Combining the Image Search with the cache system VSDIF can scan 10 000 images in seconds. A FREE demo is available for download at the company’s web site.
